The K2 has become a legend in Europe as everywhere in the Amateur radio world. Compared to commercial ready built rigs most operators prefere the K2 because its excellent receiver. Because I was an official elecraft field tester, I started with a very early K2.(serial number 0009). For sure my test review in the German Ham Radio Magazin helped to succed the K2 so well in DL-Land. Outside USA the biggest population of K2 you will fin in Germany.

The k2 is very easy to build. Even not so expierienced builders will succed building a K2 with a little help by QRPproject support. Take your chance to build the Transceiver you dreamed about all the time.

If you run into problems, QRPproject Warranty of Functionality (WoF) will insure that you will end up with an fully functionally K2. If you cant fix a Problem, we will fix it under our Warranty of Functionality for you. You have to pay a fix fee plus shipping cost only.

If you want, we can do the alignement procedure for you. See the alignment price in the price list (additional shipment cost)

K2 are available from our Berlin stock
